Areas We Serve

Marchington Excavation is based in Pakenham, Mississippi Mills, and provides septic system installation, excavation, drainage, and lot clearing services to residential and commercial properties throughout eastern Ontario.

Lanark County & Mississippi Mills

We serve all communities within Lanark County, with a particular focus on Mississippi Mills where we're based. In Mississippi Mills, we serve Pakenham, Almonte, Appleton, Blakeney, Clayton, Cedar Hill, Ramsay, and all surrounding rural areas. Across the wider county, we serve Carleton Place, Smiths Falls, Merrickville, Beckwith, Lanark Highlands, Middleville, and Hopetown. Lanark County's rural landscape means most properties rely on private septic systems, and the area's varied soil conditions — from sandy loam to heavy clay to Canadian Shield rock — require experienced installers who understand the local terrain. Septic permits in Lanark County are administered by the Mississippi Valley Conservation Authority (MVCA).

East Ottawa — Cumberland, Rockland, Embrun, Vars & Limoges

We serve Cumberland, Rockland, Embrun, Vars, Limoges, Navan, and surrounding communities in east Ottawa and Prescott-Russell. This rapidly growing part of eastern Ontario has a mix of established rural properties and new developments. Septic permits in this area are typically handled by the South Nation Conservation Authority or the City of Ottawa.

South Ottawa & Leeds-Grenville

We serve Manotick, Greely, Kemptville, North Gower, and Richmond. These communities south of Ottawa are experiencing steady growth, with new home construction on rural lots requiring properly designed septic systems. We work with the Rideau Valley Conservation Authority (RVCA) and South Nation Conservation Authority on permitting in this region.

West Carleton & Ottawa West

We serve all communities in West Carleton including Carp, Dunrobin, Constance Bay, Fitzroy Harbour, Kinburn, Galetta, Corkery, Woodlawn, Antrim, Huntley, South March, Kanata, and Stittsville. Many properties across West Carleton are on large rural lots with private septic systems. Based in Pakenham just across the Mississippi Mills boundary, we're minutes away from Carp, Kinburn, Galetta, and Fitzroy Harbour.

Smiths Falls & Merrickville

We serve Smiths Falls, Merrickville-Wolford, and surrounding communities in the southern part of Lanark County and Leeds-Grenville. Many properties in this area rely on private septic systems, and the mix of river-bottom clay and variable terrain requires experienced installation.

Ottawa

We serve all rural and suburban communities within the City of Ottawa where private septic systems are in use.
